Clojure is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multi-threaded programming.

Since Clojure is a compiled language it allows you to compile code to JVM bytecode without any issues. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection.

Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures.

When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multi-threaded designs.
